First, the heart beats faster when running. I believe that anyone who has had running experience will know that breathing is very rapid when running. This is because the muscles in the body are heating up when running, which leads to more energy and more oxygen. So when running, the heart will run very fast, so the oxygen supply in the body is more adequate. The function of the heart is to send red blood cells in the body to all parts of the body. Red blood cells carry oxygen. Therefore, the amount of exercise in the heart will also increase when running, which will lead to the phenomenon of palpitation and shortness of breath. In the face of this situation, there is no need to worry too much.
Second, whether there is physical condition after running. Of course, the point above 1 refers to people who are in good health. If they are in poor health, what are the reasons for these situations when running? In fact, there is a very common situation, and that is anemia. When you are anemic, the sugar in your body is not enough, which will lead to your poor health and you may feel very tired every few steps. This is the famous manifestation of anemia. Of course, anemia is not the only manifestation. This manifestation is the most common anemia, and there are other related manifestations, which need patients to understand according to their own relevant situation. For example, running without breakfast in the morning may lead to anemia.
Third, proper exercise. In fact, you need to exercise properly according to your physical condition. Don't just do high-intensity exercise at once, which may increase your physical burden and make you unable to bear the effect of such exercise. Therefore, proper exercise can make you healthier, otherwise it will be counterproductive.
